6 Claims. (Cl. 20-42) This invention relates to improvements in windowstructures and has particular reference to awning-type or projectedwindows.

One of the principal objects of this invention is to provide a novelawning-type window wherein the opening and closing of two or more sashesor ventilators is controlled by manipulation of one of the ventilators;

Multiple operated awning-type windows have been proposed heretofore .buthave not proven entirely satisfactory due to certain inherentdisadvantages. For example, it is necessary, in order to operablyconnect together the two or more ventilators of each window, to utilizespace-consuming linkage arrangements which must be shielded to eliminatethe unsightly appearance of the linkage structure. The shielding andlinkage structure contained therein is positioned interiorly of thebuilding and presents problems with regard to screening, inasmuch as thescreening must be on the inside of the window. Accordingly, withpresently commercially available multiple operated awning-type windows,the screening must be such as to encompass the linkage structure, andhence the entire window. From a standpoint of expense and appearance,this is undesirable, since generally one of the lights of the window isstationary, yet must be unnecessarily screened. Such structures arefurther disadvantageous in that they are relatively complicated from amechanical standpoint, present installation and maintenance problems andare relatively expensive. In other installations, due to the limitationsinherent in the structure thereof, it is necessary to use an expensivedummy ventilator for the stationary light in order to permit theoperative connection between the movable ventilators to be made. One ofthe principal objects of this invention is to provide a multipleoperated awningtype window which is not subject to these disadvantages.

Another object of this invention is to provide a multiple operatedawning-type window in which the moving parts are all behind the frameinside the building structure so as not to be exposed to the weather.

Another object of this invention is to provide a window of the typedescribed in which the moving parts thereof may be removed therefrom andre-installed therein from the inside without affecting the buildingstructure itself.

Yet another object of this invention is to provide a multiple operatedawning-type window which is simple in construction and hence relativelyinexpensive, easy to install and maintain, yet which is highly'etfective in operation.

Other objects and advantages of this invention it is believed will bereadily apparent from the following detailed description of preferredembodiments thereof when read in connection with the accompanyingdrawings.

Figure 9 is a sectional view taken substantially on the line 99 ofFigure 8.

Referring now to the drawings, the numeral 10 designates a window frameas a whole, embodying a sill section 11, side jambs 12 and a header 13.The several sections are rigidly connected at their abutting ends anydesirable manner, such as by angle brackets or the like '(not shown).The window frame is mounted and secured in the preformed wall or otheropening in any conventional manner. The frame is preferably rolled,extruded or formed metal.

The sill, jambs and header are each of similar shape, comprising outerand inner flanges 15 and 16 respectively, and a web member 17 connectingthe flanges.

The closures for the window forming a preferred embodiment of thisinvention comprises an upper sash or ventilator 20, an intermediatefixed light 21 and a lower ventilator 22 operably connected to the upperventilator as will be described in detail below.

The frames of the ventilators are constructed of the same type ofsections as the window frame 10. Thus, the upper ventilator framecomprises upper and lower members 25 and 24, and side members or stiles26. Similarly, the lower ventilator frame comprises upper and lowermembers 29 and 28, and side members or stiles 39. The fixed light 21 iscomprised of the side jambs 12 and upper and lower meeting rail members33 and 32. It will thus be understood that a dummy or a fixed ventilatoris not required.

Means are provided for operably connecting the ventilator 20 to thewindow frame, and as shown in the drawings, these means may include thesliding shoe assemblies 38 and balancing arms 39. It will be understoodthat the means for connecting each side of the ventilator to therespective jamb are identical, so only one will be described in detail.

Secured to the upper frame member 25 of the ventilator 29, by means ofscrew members 40 is an anchor block 42. The block extends outwardly fromthe end of the frame member and carries an integral stub shaft or pin43. The web 17 of the jamb is provided with an upper vertical slot 44through which extends the shaft 43. A stabilizer shoe 45 is journalledon the shaft and is urged into contact with the exterior side of thejamb web 17 by means of a helical spring 47, one end of which bearsagainst the shoe. The other end of the spring bears against a crank orlever arm 49 which is rigidly connected to the end of the shaft 43,preferably by means of welding.

The balance arm 39 is pivotally connected at one end to the jamb web 17by means of a pin 52, and similarly pivotally connected at the other endto the ventilator side member 26 by means of screw member 54 and washer55.

From the description thus far it will be understood that the ventilator20 is operably connected to the frame 10 for outward opening movementwith respect thereto. That is, as the lower portion of the ventilatorswings outwardly, the upper portion thereof moves vertically downwardlyby virtue of the sliding connection between stood that by reason of theshoes 45 and springs 47, the

ventilator is centered and. stabilized through tension thereof. Thelower, part'of the groove 44 isiwidened as at 60 to permit the shoeassembly to, be removed therethrough for service or repair During normaluse; this widened portion 60 is covered by a plate -61, secured totheweb 17 by means of screw members '62,.vwhich plater functions as astop and weathering member. 11

The lower ventilator '22 is connected to the window frame in'a manneridentical to that described above with respect'to the upper ventilatorv20. Thus, a balance arm 65 is pivotally connected to the lower portionof the jamb web 17 and to theside member 30, and a sliding shoe assembly67 operates in a slotv 68 in'the web 17. A lever arm 69fisrigidly'connected to the stub shaft (not shown) of the shoe assembly167. It will again be understood that the ventilatorfconnecting membersare duplicated on each side thereof. The upper and lower ventilators 20and 22 are connected together for simultaneous operation by means of anadjustable link member 70 which is pivotally connected at the upper andlower ends thereof, by means of bolt members 71 and 72, to thefleverarms 49 and 69 respectively. The bolt 72 extends through a vertical slot73 in the lower end of the link member 70, thus providing a means ofadjustment of the relative positions of the lever, arms 49 and 69, andinturn, the ventilators 20 and. 22. The linkage assembly, whichcomprises the link member 70 and the lever arms 49 and 69, is enclosedin a cover member 80 suitably supported on a bracket element 81..

The above-described structure, which permits the linkage assemblies tobe located to the sides of the window frame, enables use of simple,individual inside screens 85 and 86 for the'ventilators. This structurealso permits the omission of .any screening covering the fixed light 21.Preferably, the lower screen 86 is of the sliding wicket type to permitready access to the ventilator 22.

In operation, by manipulating the lower ventilator 22, the upperventilator 20 is simultaneously and similarly operated through thelinkage assembly.

A modified formof the invention is diagrammatically illustrated inFigure 8. 7 Here again, the window includes an upper ventilator 100, alower ventilator 101, and an intermediate fixed light 102. Here,however, the upper ventilator is mounted to move outwardly, while thelower ventilator is mounted to move inwardly. The upper ventilator 100is identical to the ventilator 20 previously described, and is similarlyconnected to the jamb' 106, being provided with a sliding shoe assembly103, balancing arm 104 and lever arm 105.

The lower ventilator 101, on the other hand, is pivotally connected tothe jamb 106. As shown best in Figure 9, an anchor block 107 is securedto the lower frame member 108 of the ventilator 101 by means of screwmembers 109. The block extends outwardly from the end of the framemember and carries an integral stub shaft or pin 110. The web 111 of thejamb 106 is provided with a slot 112, which permits the block and itsassociated parts to be disassembled from the ventilator afterinstallation. A cover'plate 113 secured to the web 111 normally coversthe slot 112 and, additionally, is provided with an aperture 114 throughwhich extends the pin 110, the cover plate thus further functioning as apivot for the pin 110 and hence also the ventilator 101. Rigidly securedto theend of the pin, as by welding, is a lever am 115.

The upper and lower ventilators 100 and 101' are connected together forsimultaneous operation by means of an adjustable link member 120 whichis pivotally connected at the upper and lower ends thereof, by means ofbolt members 121 and 122, to the lever, arms 105 and 115. The entirelinkage assembly is preferably enclosed in a cover member (not shown).

It will be noted from an inspection of Figure 8 that when theventilators are in the closed position, the lever arm 115 is inclined atan angle of about 30 from the horizontal, and further, that the arm .115is approximately twice the length of the arm 105. This is to compensatefor the fact that the upper ventilator 100 both pivots outwardly andslides downwardly in operation, whereas the lower ventilator 101 hasonly a pivotal motion. By means of the structure shown, both ventilatorssimultaneously open to the same extent.

It will be understood from the above description that V simple ,yethighly efiiective multiple operating awningwhich is entirely protectedfrom the weather, paint and V the like.

By virtue of the same structure, the shoe assemblies and other movingparts maybe lubricatedwithout marn'ng the appearance of the'sash, and,if desired, the moving parts may be removed from the inside without anychange in the building structure. It is also apparent that the operatingor linkage assembly is especially adapted to be contained within acompact, unobstructive housing or cover. As has been pointed out, thestructure permits the use of screening directly attached to the frame,and only where needed. Moreover, the described structure is so' designedas to eliminate the pos sibility of the ventilators falling'out of theframe upon failure or arm breakage and/or shoe failure.

While the invention has been described as applied'to only twosimultaneously-operated ventilators, it will be readily apparent tothose skilled in the art that more than two ventilators may be connectedfor multiple operation in the same manner. Also, if it is desired toopen the ventilators inwardly, rather than outwardly, this may beaccomplished by a simple reversal of the respective positions of theshoe assemblies and of the balance arms, with respect to theventilators.

Having'fully described my invention, it is to be understood that I donot wish to be limited to'the details herein set forth, but my inventionis of the full scope of the appended claims. I
